25 mins late. The flight attendants were chatting and laughing loudly at the rear, which was rather unpleasant.

25 mins late. The flight attendants were chatting and laughing loudly at the rear, which was rather unpleasant.

The flight was excellent, the crew was super friendly. The only complaint I have is, 3 of my zipper handles were broken and there were 2 massive scratches on the back of my bag

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

Empty seats next to me - wish it had been for a longer flight!!

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

You should not have to pay for WiFi in business class

The plane. Airbus A330-200. Comfortable for a 7-hour flight. Seats seemed to have more legroom. I was in row 17. Flight was operated by Delta but was better than expected.

It was nice to be on a legacy airline, people try at least.

My baggage (1) didn’t arrive with me. I am waiting for it.

Level of cabin service was poor for what i'd expect from Business Class. had to go to galley to ask for beverage or refills. Final outbound service wasn't fully served because service was started late, as a result of the crew taking a break later than planned during flight and having compressed time before landing (no clear how this poor planning was possible on a 10 hour flight). Seat comfort was poor compared to Emerates and Ithiad

This is just for first leg, second leg from London Heathrow to Delhi was the worst.

The seats often do not function - in the premium economy the seat does not lean back. The passenger in front of me decided to come and sit next to me on his own volition because his seat was not leaning back.

The sitting for business class was very poor. It was cramped. Some of the seats were defective and could not be kept perfectly upright. If the passenger in front reclined, the passenger behind was trapped in a narrow space. I would consider other airways in the future.

Disappointed as we discovered when checking in at the airport 6hrs before the flight was scheduled, that we had been offloaded onto standby after having purchased these tickets months in advance. We had tried checking in online the night before but were unable to. BA had obviously over sold the seats, and we were told they couldn't confirm we could get on the flight until check in closed. Eventually we did get on but were not seated together. That was a bit of stress we just didn't need.

My flight from Athens to London was delayed 30 minutes. I got automatically booked on a different flight before the plane landed. However, I never received any notification about the new booking so I had zero knowledge about the flight number or even where to go. Checking in: it was absolutely impossible to check in for my flight online. I literally had to call British Airways to check in for my flight and select a seat. It was very inconvenient and a bit stressful.

I ordered a drink, but never got it. I ask what type of drinks they had and they could not tell me and there was not printed copy that I could find that is usually on most airplanes. They served dinner and never walk back to see if any need a drink or anything afterwards until they served the snack just before landing.

The flight was very delayed in taking off - which was out of control of the crew, but then the pilot worked hard so we only arrived about 30 minutes late. Everyone was very friendly and accommodating!

Flight was canceled with little notice or explanation. There were no other flights to Belfast from Heathrow, so I had to travel across town to London City (or wait until the next day).
